IMPROVEMENT IN REGISTER-Politics Foriy PRINTING-PRESSES.

The Schedule referred to in these Letters Patent and making parl: of the same.

To all whom. it may concern:

Beit known that I, ANDREW OVEREND, of the city and county of Philadelphia, and State of Pennsylvania, have inventedv certain new and useful Improvements in Machinery for Pointing Sheets of Paper, where they are to be folded, or where they are required to be marked or registered for any other purpose; and I do hereby declare that the following is a full, clear,-and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- L Figure l, is a side elevation; Figure 2, a front elevation; and The other figures represent parts separately, and will-be referred to hereafter.

The same letters indicate like parts in all the figures. My said invention is for the purpose of making pointholes in sheets of paper, after they are placed in position on the feed-board either of a printing-machine, a folding-machine, or any othermachine' to which it may be desired to present sheets of paper that have been marked.e

In the accompanying drawingsa represent-s a suitable frame, and b, an inclined board, which -may be the feed-board of a printing-press or of a paper-folding or cutting Inachiue, and on which the sheets of paper to be marked are placed.

rock-shaft, c, having at one end fa short arm, d, to which -a connecting-rod, e, is pivotedfand the said connectingrod, at its lower end, is provided with a friction-roller, f, which rests on the periphery of a cam, g, on the end of a shaft, h, which may be one of the shafts of the machine to which the sheets of paper are to be fed, or receiving motion in any suitable manner.

The said ca1n.g,for the greater part of its circumference, is concentric, to hold up the pointer, to be presently described, during the time that a fresh sheet of paper is placed on the inclined or feed-board, and the remaining part of the periphery of the said cam, as at i., is cut away to a sufficient depth to permit the pointer to come down on to the inclined board, and both sides of this depression are curved, as"r`epresented, tn depress and then to lift the pointer. As represented in the accompanying drawings, the point-cris depressed, when permitted bythe cam, by the force of gravity of the parts, as that will be found suflicieut, but, if desired, a spring may be added, to insurethe depression, or to give it morcforce, if required.

The rock-shaft c carries an arm, yfsecured thereto by a temper-screw, le, so that it canfbe adjusted to any desired position ou the rock-shaft.

To this arm is secured a series of brauch-arms, ll'l, connected thereto by screw-bolts passing through slots, t'o admit of ready adjustment. arms are represented in gs. 1 and 2 ofthe accompanying drawings, but the number may be increased or diminished at will.'

Each branch-arm, and near its outer end, is armed with a pointed spurfm, and with a spring-shield, n. Theseshields, in their normal position, project alittle below the points ofthe spurs, and have a hole, through which the points of the spurs can pass when the springshields' yield. Y

Small disks o, of leather or other suitable material, having holes in them for` the reception ofthe points of-the spurs, are fastened, by glue or other suitable means,'to the surface of the inclined or feed-b0ard, wherever the holes are required to be made in the paper, and the branch-arms adjusted, so that, when the branch-arrns are depressed quickly, the spring- Shields shall yield, and permit the points of the spurs to strike through the paper and into the holes in the said disks. The spring-shields, by reaction, immediately lift the arms, and draw the points of the spurs lifts the arm j. The sheet of paper, it will Abe seen, is supported all around on the under side, where and at bthe time it is being punched, and also on the'upper At the back edge of this board, there ismounted a side,.by the spring-shields, while the points of the spurs are being drawn out.

If found desirable, two or even more arms 7' may be used on the rock-shaft, and also, instead of the brancharms Z l l, the arms may be connected by one or more cross-bars p 1), as in iig. 3, having slots or holes in them, in which the spurs are secured. Thus, by moving the cross-bars in or ont on the arms j j, and moving the spurs lengthwise in the cross-bars, any part of the 4sheet in which it is desired to make points can be reached.

l. The combination, with the rocking arm j, of a series of points, m an., to puncture the paper upon the feed-board, ,by a propel' movement of the arm j, and the springs fa n., for stripping the paper from the points, substantially as described, and for the purpose specified.

2. The eombiluttiou, with the rocking armj, provided with points on m and strippers n u, of the disks o o on the feed-board, substantially as described, and for the purpose specified.
